Abstract:The present paper focuses on the fundamental scientific problems of the structural safety and disaster prevention in the preservation of historical architectures. The risk analysis of disasters, the scientific basis of material failure and structural damage, the response analysis of structures under stochastic disaster actions, and the assessment of structural system reliability against hazards are emphasized regarding their necessity and significance of protection research of historical buildings. The frontier technologies in structural engineering which should be particularly concerned about in the research of structural safety and disaster prevention of historic architectures are systematically reviewed, and several possible development technology directions for deep study afterwards are proposed as well.
